Antiarrhythmic agents

Antiarrhythmic agents are medications used to restore and maintain a normal heart rhythm when irregular beats, or arrhythmias, occur. They work by affecting the electrical signals that control heartbeats, either slowing down, speeding up, or stabilizing these signals. Different classes of antiarrhythmic drugs target specific parts of the heart's electrical system to prevent abnormal rhythms, reduce episodes, and improve overall heart function. These medications are essential in managing arrhythmias but require careful monitoring due to potential side effects and the complex nature of heart electrical activity.
